Bevel 788 gusset
Strip plastic and edge deburr 7112 skin.
Cleco 787 rib to 706 bulkhead.
Start clecoing 7112 skin to fuselage

Back when doing the aft bulkheads, I had edge deburred the 787 rib and made a 708B bracket. I drilled it to the rib. I got it wrong. The fore/aft spacing is not right.

THAT's why the instructions have you make it now and then clamp and drill. It's just a short piece of angle with two holes drilled in it. Easy enough to do again.
